Tennessee Code Title 12. Public Property, Printing and Contracts § 12-3-505

The chief procurement officer is authorized to purchase for a state governmental entity in the open market specific goods or services for immediate delivery to meet emergencies arising from any unforeseen cause, including, but not limited to, delays by contractors, delays in transportation, unanticipated volume of work, and acts of God. The chief procurement officer may delegate this authority to any state agency; provided, that a report on the circumstances of any such emergency and the actions taken by such state agency as a result of the emergency shall be transmitted in writing as soon as possible by such state agency to the chief procurement officer. The report shall set forth the prices at which goods and services were purchased and the total amount of the purchase. The chief procurement officer shall keep each report on file in the permanent records of the central procurement office. All emergency purchases shall be posted on the single public internet website in such form as prescribed by the procurement commission. All emergency purchases shall, if practicable, be made on the basis of competitive procurement.
